Ebullient, Inc., announced today that it raised $2.3 million to expand its presence in the data center cooling market.

According to a release, the investment was led by a private investment group with ties to Aspen, Colo., existing investors and longtime supporters.

The Madison-based company created a cooling system in which low-pressure fluid is pumped through flexible tubing to sealed modules mounted on processors in each server. The processors produce heat, which the fluid transports back to a central unit, where it’s either rejected outside the facility or reused somewhere else in the facility.

Ebullient earned Qualified New Business Venture status in 2013.
